[Academics][Excellent R&D] Developing Revolutionary Energy Harvesters

As it is a global agenda to adopt a lifestyle that is more environmentally friendly, developing technology that allows eco-friendly processes and production outcomes has also shifted into focus. Professor Sung Tae-hyun's (Electrical Engineering) research on energy harvesting technology is a prime example that shines a ray of hope onto our path of sustainable development. According to research from Cambridge University, only 12 percent of electric power generated from a power plant is used, while the other 88 percent goes to waste. Consequently, "energy harvesing," the idea of saving and using the wasted energy, has become a crucial research topic for more effective and efficient use of energy generated. It would eiminate concerns about creating a completely different type of power plant or unintentionally harming the environment. "Energy harvesting technology will allow us to convert various types of wasted energy into usable energy,” said Sung. Sung Tae-hyun (Electrical Engineering) explains the different types of energy and how massive an amount of it is wasted. There are different types of convertible energies such as piezoelectric energy (electric energy created from vibration), heat energy (electric energy created from heat), and photovoltaic energy (electric energy created from lighting). Sung focused on piezoelectric and photovoltaic energy when researching energy harvesting technology. The purpose of his research was to successfully create an "energy harvestor" with a sensor that detects the different types of energy, then converts them accordingly to electric energy that is entirely usable and more environmentally friendly. “Sensor technology is actually the core of the Fourth Industrial Revolution since everything is connected through internet of things (IoT). It can detect anything anywhere without limitations, and that’s what would make the energy conversion process more efficient, especially in places where all types of energy are generated.” Energy harvestors demonstrated in a smart factory (Photo courtesy of Sung) Sung is in charge of Hanyang University's (HYU's) SEED laboratory that researches energy harvesting technology. In 2011, it even broke a record for retaining the world’s best piezoelectric energy harvesting data. According to Sung, he approached the energy waste problem by first communicating with the workers in the field, detecting and redefining the problem at hand, moving on to the ideation process, creating prototypes, and then testing it out to see if it was realistically applicable and effective. Sung is now in the process of testing out the developed energy harvestors in four big industries such as LED production, smart factories (industry where the whole production process is combined with digital automation solutions), and industries where both offices and production scenes are located in the same building and power plants. “Currently, we are working on the development and commercialization of applicable IoT sensors applied to energy harvestors, but we hope to create harvestors with massive energy conversion capacity in the future. Not letting any energy go to waste is the main goal,” said Sung. Sung explains the application process of energy havestors in various industries. Behind Sung’s passionate research, there was a strong drive that was truly inspirational. “Our lab is called the SEED lab, like the seed in an apple. You may know how many seeds are generally in an apple, but you never know how many of them will actually become an apple. It is the work of a miracle, and that is the kind of miracle that our lab members wish to achieve together. I ask myself, what kind of fruit am I expecting in 10 or 20 years when I’m planting this seed? In other words, what is my goal in life that takes the form of the fruit? There are so many people that eat the seed before it grows just to fulfill their self-interest. I’d say that those people are myopic, as they may be full and satisfied for the moment, but they will not be in the future. It sure takes a long time to grow and harvest the seed, but once it grows and starts to bear fruit, a never-ending cycle begins. One seed will bear hundreds of fruits ever year. So the next question is, how will you use these fruits? For me, that’s the question of what I want to achieve in my life, and my life goal is to give back the fruits I’ve harvested to the society, and spread the happiness.” Sung talks about his beliefs and philosophy, ending with some inspirational advice for Hanyang students. “I hope that I can share this belief with the Hanyang community. I hope that we can work together to grow the seeds of Hanyang into a strong tree that will bear many fruits, and spread the miracle to the world. That being said, I would like to tell the students not to be afraid of failure, to have a life-goal that can change the world, not to be devastated from failure, to always be positive but not conceited nor arrogant, and to love challenges. Our body is systematically goal-oriented, and once we have a goal, it becomes our drive to keep going even when we are tired. On top of that, if you think that our purpose in life is for the happiness of our community, then you will become a true global leader.” Park Joo-hyun julia1114@hanyang.ac.kr Photos by Choi Min-ju

[Performance]A Trophy at Last

Hanyang University (HYU) boasts many talented athletes, and the volleyball team has many of them. After many years of hard work, the university volleyball team won a trophy in this year’s Cheongyang National Volleyball Competition, defeating its rival 3 to 1 in the final play-off. The competition was held in Cheongyang-gun from July 16th to 23rd, co-hosted by the Korean University Volleyball Federation (KUVF) and Cheongyang County Volleyball Federation. Among the players, the competition is commonly referred to as "the second competition." This is because there are two competitions during each summer vacation, aside from the year-round tournament during the spring and fall semesters. HYU volleyball team was not able to make it to the final round during the "first competition." Surprisingly enough, this is what has been happening with the team for several years. Director Yang Jin-woong commented, “Although their final rank was 6th, defeating last year's champions on the way boosted the team’s ego a lot.” The team captain let the director take the credit. “The training got much more organized and made it possible to win,” smiled Ryu Seong-ju (Sports Industry, 4th year). Ryu Seong-ju (Sports Industry, 4th yr), the captain of the volleyball team, commented that he wants to make it to the play-off this year and bring home a prize on August 1st. The toughest match in the competition was the final round, where HYU met Kyunghee University. “Our players couldn’t even move their legs in the first round,” reminisced Yang. That fear did not come from the loss to Kyunghee during the home-and-away matches earlier this year, but the fact that they had never made it to the final round. But with the director’s fierce encouragement, the players were able to play as well as they had during practice. The captain also revealed a secret source of encouragement from the coach. “He promised the team two more days of vacation and 1 million won prize money. That really raised the team spirit,” laughed Ryu. Both the director and the captain showed confidence for the coming home-and-away games. Ryu emphasized that although the HYU volleyball team did not make it to the play-offs for the past four years, it seems highly possible this year. “When I was on the university volleyball team, I was proud to be part of it. I will work hard to get that glory back,” said Yang with contentment. The upcoming season starts when school starts again and runs until October. Wish the team luck!

[Academics][Researcher of the Month] Observation of Unique Properties of Anti-PT-Symmetric Systems

Professor Song Seok-ho (Department of Physics) has recently announced his research on the observation of an Anti-Parity-Time (APT)-Symmetric exceptional point and energy-difference conserving dynamics in electric circuit resonators. When dividing an electric circuit in half, the two parts show a symmetric stream in both time and space. This is referred to as Parity-Time (PT) Symmetry, which enables electricity to flow in the same stream in both directions inside an electric circuit. By "breaking" the unidirectional converter, the symmetric stream of the forward and backward propagation differs, and the PT-Symmetric form is broken. This picture shows the breaking of the Parity-Time (PT) - symmetric form and how the flow of light changes. By breaking the symmetric middle part, the forms of foward and backward propagation differ, which allows for the creation of diodes. (Photo courtesy of Song) Breaking the PT-Symmetric form allows for the creation of diodes which are semiconductor devices that allow electricity to flow only in one direction and prevent any form of backward propagation. Being a key element of the flow of electricity within an electric circuit, the creation of photodiodes has been a long-term goal in the field of nanophotonics. Based upon the idea of substituting electricity with light, which would allow electric devices to be used with higher speed and energy efficiency, nanophotonics have long been troubled with a loss of energy due to the absence of diodes which allow the efficient flow of energy. Thus, Song’s current research of creating diodes through the "breaking" of PT Symmetries has significance, as it may provide a foothold for the creation of photodiodes. Song has verified his research by successfully breaking symmetries within electric circuits formed with resistance-electric condensers. The experimental process was made as simple as possible based upon the professor’s belief that easy verification leads to easy commercialization. “It is the process of thinking out ideas that should be given effort, whereas the experimental process should be done with ease,” explained Song. This can be seen in the fact that only simple devices with educational purposes were used in the verification of this research. Professor Song Seok-ho shared his research philosophy of the making process which should receive the bulk of time and effort. On the other hand, he mentioned that the experimental process should be conducted as simply as possible, as simple verification leads to simple commercialization. When asked of his future plans, Song explained how he has managed to break through one mere field of nanophotonics. He also maintained that “there are so many fields to overcome. By applying concepts to each field, breaking through the current limitations of physics is my next goal.” Succeeding with the observation of anti-PT-symmetries, it does not seem like it will be long before Song provides another foothold towards a novel breakthrough in the field of nanophotonics.

[Event]HYU Hospital Free Lecture and Cancer Screening

Hanyang University Hospital organized a free lecture and cancer examination on Friday, July 27th, which was World Head and Neck Cancer Day. It was the second year the hospital hosted an event to raise awareness of head and neck cancer to the public. Four doctors from different hospitals joined this event, and 34 people were examined to check if they had any cancer or other issues in their head or neck. Head and neck cancer is not as well-known as other cancers like breast cancer or lung cancer. It is because this type of cancer is not as prevalent. However, head and neck cancer does occur, more and more so recently. Early discovery and treatment is the key, which is why experts in the field gathered and created World Head and Neck Cancer Day four years ago. HYU hospital was the first to celebrate it in Korea last year, which influenced other hospitals to join in this year. Professor Jung Pil-sang (Korean Society of Head and Neck Surgery) is giving a lecture on Friday, 27th July at Hanyang University Hospital. One of the highlights of the event was the part where patients who have overcome different types of head and neck cancer shared their experiences with the crowd through video testimonials. Kim, age 59, attested to a lucky discovery during his ultrasound test, and how he now goes around and helps others quit smoking. More than 65 percent of the cases of head and neck cancer are caused by alcohol and tobacco use. Tae Kyung (Department of Otolaryngology), as one of the organizers of the event, emphasized that “more than 80 percent of head and neck cancer is related to smoking habit.” Tae Kyung (Department of Otolaryngology) mentioned, "It is important to trust the medical staff and not rely on information from the internet for the treatment to be efficient," on Friday, 27th July at the World Head and Neck Cancer Day event. (Photo courtesy of Tae) The following are symptoms of head and neck cancer that require an immediate visit to the doctor. Change in voice for three weeks or more A mouth ulcer that doesn't heal after three weeks or more Oral swelling that lasts three weeks or more Reddish white patches inside the mouth Difficulty swallowing for three weeks or more Congestion on one side of the nose with drainage Teeth chattering without a clear reason Enlarged lympnodes lasting three weeks or more Lump on the eye lid or near the eye Ear pain or trouble hearing for three weeks or more Tae mentioned that he is “excited to spread awareness about the cancer so that more people will be able to treat the disease before it’s too late.” Head and neck cancer is untreatable after entering the second half of the fourth stage. He advised those suffering from the symptoms above to immediately see a doctor for a check-up. Kim So-yun dash070@hanyang.ac.kr Photos by Kang Cho-hyun

[General]Global Hanyang Summer 2018

With the rising popularity of K-pop, Korea has been getting more and more international attention. Hanyang University (HYU) definitely saw an increase in foreign students as well. HYU’s Summer International School (HISS) first started in 1990 and is now recognized as one of the biggest summer international schools in Korea with about 2,100 students attending. When HISS first opened, its program framework was completely different from the current one. According to Park Ji-young who is in charge of the summer program, HISS started out with its main focus on teaching students Korean and simply introducing Korean culture. While offering the best Korean experiences was the core objective, it has expanded to include extensive courses and a variety of extra-curricular activities. HISS students enjoying their night on the Han River cruise. (Photo courtesy of HYU Office of International Affairs) The program consists of students from 130 different majors such as Art & Design, Communication & Media, Business & Economics, Engineering, Humanities, International Studies, Korean Studies & Language, Science & Math, and Social Studies. Additionally, nine various elective courses are offered such as Taekwondo, Korean traditional fan dance and pottery. According to Park, the most popular courses are engineering and technology, business management, and media communication. To provide high quality classes, HISS made sure to select half of the professors from Hanyang and the other half from foreign universities. On top of that, there are six additional extra-curricular activities such as the Han River night cruise, Nanta performance, SM Town musicals, and a trip to Carribean Bay. Unlike other schools' programs, Korean students can also participate in the summer program. This way, they can engage with many foreign students in an academic environment, which is not a common opportunity. As for foreign students, most are from Singapore, the US, China, and Europe. For this year’s HISS, there are about 2,100 students in total, consisting of 1,800 foreign students and 300 Korean students. As there are more students from various countries participating in HISS, Park admitted that there are definitely hardships and challenges, but with the help of 40 "sumporters" (summer supporters), they are able to maintain their high quality program and guarantee the satisfaction of the students. “Accidents are bound to happen with this many students, but I hope that we will be able to develop HISS into a world-wide known program while ensuring students' satisfaction and joy, while providing unforgettable memories.” Park Joo-hyun julia1114@hanyang.ac.kr Photos by Kang Cho-hyun
